Robotic Partial Nephrectomy in Surrey
Mr Sri performs retroperitoneal robotic partial nephrectomy at Spire St Anthony's Hospital, Cheam and Nuffield Health Parkside, Wimbledon — serving patients across Surrey and South West London. Both offer the same robotic surgical programme, free or accessible parking, and easy access from the M25, A3, and A24 corridor.
Mr Sri is Kidney Cancer Lead for the South West London Network — Surrey patients accessing his private practice benefit from the same tertiary-level expertise that underpins his NHS role.
Tertiary-level kidney surgery — close to home
For patients diagnosed with a kidney tumour in Surrey or South West London, the diagnosis itself is enough to navigate without adding complicated journeys into Central London for repeated appointments. Mr Sri's Surrey practice solves this without compromise — both Spire St Anthony's in Cheam and Nuffield Health Parkside in Wimbledon are fully equipped for retroperitoneal robotic partial nephrectomy and used for complex kidney cancer surgery.
The choice between locations is purely practical. Spire St Anthony's, on the A24 in Cheam, has free on-site parking and is the natural choice for patients in Sutton, Epsom, Banstead, and the M25 corridor. Nuffield Parkside, on the A3 in Wimbledon, is preferred by patients in Kingston, Wimbledon, Wandsworth, and South West London who travel by rail or A3.
Critically, both locations offer the same surgeon, the same technique, and the same outcomes as Mr Sri's Central London practice — including for high-complexity tumours that other centres decline for kidney-preserving surgery.

The retroperitoneal approach — why it matters to your recovery
Most robotic kidney surgery is performed through the abdomen (transperitoneal), requiring the bowel to be moved to reach the kidney. Mr Sri approaches the kidney directly from behind — the retroperitoneal route — without entering the abdominal cavity at all. This distinction has meaningful consequences for patients.
Mr Sri introduced this technique to South West London, performs it as his default approach for the majority of cases, and has published on this technique in the Journal of Robotic Surgery. He is one of a small group of European surgeons operating at this volume retroperitoneally.
The numbers behind the practice
These figures represent an audit of Mr Sri's personal robotic partial nephrectomy series as of end 2025. The same outcomes apply across all three of his clinic locations.
Treating the full complexity spectrum
As SWL Network Kidney Cancer Lead, Mr Sri accepts tertiary and quaternary referrals from across the region for tumours declined for nephron-sparing surgery elsewhere. His case mix reflects one of the most complex partial nephrectomy practices in the UK.
| RENAL Score | Complexity | Proportion of series |
|---|---|---|
| Score <7 | Low | 8% |
| Score 7–9 | Intermediate | 44% |
| Score >10 | High | 48% |
Median tumour size 3.2cm (range 1.5–9.0cm). 32% of tumours >4cm.
Told your tumour can't be preserved?
A significant number of patients seen at Spire and Nuffield Parkside have been assessed — and declined for kidney-preserving surgery — at other hospitals in Surrey, South West London, or further afield. Mr Sri reviews these cases on their merits at his Surrey clinics. The conversion to radical nephrectomy rate in his series is 0.3%.
Patients who have received a recommendation for radical nephrectomy, or are on active surveillance and wish to discuss whether surgery is appropriate, are welcome for a second opinion at either Surrey location. No GP referral is required.
Why saving your kidney matters beyond the operation
Removing a kidney tumour while preserving the rest of the kidney is the standard of care recommended by the European Association of Urology (EAU) for the majority of renal masses where it is technically feasible. The evidence for long-term patient benefit is substantial and independent of cancer control.
Every functioning nephron preserved contributes to glomerular filtration rate (GFR). Chronic kidney disease (CKD) — which results from reduced nephron mass after radical nephrectomy — is independently associated with increased cardiovascular mortality, accelerated hypertension, and the need for dialysis. Partial and radical nephrectomy achieve equivalent cancer control for most kidney tumours: the long-term outcome difference lies in kidney and cardiovascular health over decades following surgery.
Mr Sri's commitment to nephron-sparing surgery extends to the most technically demanding cases — including large, endophytic, and hilar tumours where many surgeons default to radical nephrectomy. His trifecta and pentafecta data confirms this approach can be delivered safely even in high-complexity cases.
EAU guidelines state that nephron-sparing surgery should be performed for all T1 renal masses where technically feasible, and strongly considered for T2 tumours where expertise allows.
Radical nephrectomy is reserved for cases where partial nephrectomy cannot be performed safely without compromising oncological control.
